To all whom it may com-mm:

Be it known that 1, James Urrnmium, a citizen of the United States, residing at the city of New York, in the borough of Man haltau and State of New York, have invented certain Jn-w and useil ul improvements in lype-\Vriting Machines, of which the following is a. full, clear, and

This invention relates to tahulating at taclnncnls for lypowriting machines, the object being to provide a simple form of mechanism which can be easily attzwhetl to existing machines or mnstructcd as a part of the nulehine itself, and by means of which the trmcling portion of the machine can he instantly made to jump from any position in the line of writing to the exact position for writing the first figure or character, in a number or word to be located in a certain column of figures or words on the sheet. I accomplish these objects in the particular constructions shown by means of a graduated stop or stops adapted to be fixed at any desired point on the scale to determine the columnar field, in combination with a single plunger adapted to be thrust into the path of n'iovenicnt of the stop, a certain distance toengage with. a certain graduation on the stop, by means of an associated one of a se ries of keys which are arranged to throw the plunger to respective graduated distances corresponding to the graduations onsaid stop.

The invention also consists of other combinations involving the carriage releasing devices, all of which will be fully hereinafter described and claimed.

To the above and other ends which will hereinafter appear, my invention consists of the features of construction, arrangements of parts and combinations of devices set forth in the following specification and partioularly pointed out. in the appended claims.

In the accompanying drawings: Figure 1 is a plan of one style of ty'pewritin ma.

chino equipped with my improved ta ulating device; Fig. 2 is a contra vertical, front to roar scct1onal view of the'machme and including the-rclcasmg lever; Flg. 3 1s a per spccti've view of the lar er portion of the .tahulating attachment; *ig. 4 is a frag} n cntary, vertical, front to rear, sectional view illustrating a slight modification of the tabulating attachment adapting it for a cercxect ilesmription.

tain style of machine; Fig. 5 is a' ilan of a. machine of another style, fitted wit a tabulaling attachment in accordance with my invention but modified to suit theparticular style of machine; Fig. 6 is a vertical, front to rear scctirmal view of the construction shown in Fig. 5; Fig. 7 is an enlarged plan of the modified form of tabulating device; Fig. 8 is a detail of the detcnt or denominational. selecting stop applying thereto; and Fig. 9 a detail of the shipped or graduated stop.

In Figs. 1 to 4 the tabulating device is shown applied to the Well-known Remington style of machine, wherein A indicates the frame, B the usual character keys and C the platen mounted in the carriage C which traverses the rails 0' and c". Pivotally supported on the carriage is the usual feed rack c which is engaged by the pinion c for the usual step-by-stepmotion. The pinion is secured to the forward end of a shaft 0* l which carries an escape wheel 0 operatively l connected to the shaft and actuated by the feed dogs a on the pivoted arm or dog rocker 0, the arm being moved by the key levers through the usual universal bar 0 and connecting links 0", a restoring spring 0 moving the parts back to normal osition.

The feed rack 0 is pivoted on t e shaft 0 from which 1 have extended rearward suitable arms supporting a release bar 0" extending the width of the carriage. The rack can be lifted out of engagement with and downward, the carriage being than free to traverse its rails under the action of the usual spring drum c and steel tape a.

At the real-of the carriage I provideastop bar a havin a serrated face a and upon which is mar hed a scale corresponding to the usual scale at the front of the machine. Upon this bar ma be secured one or more detachable blocks which I shall hereinafter refer to as stops. The stop is undercut I and provided with internal serrations which y engage with those on the bar and by the aid of the spring clip b which are bent as indicated in Fig. 2 to engage under one corner or edge of the sto bar to hold the stop against accidental on the bar where the stop may be locatcd. The rear side of the stop is inclined in a dil rection ranging from. right to left, and this etachment at any point the pinion by pushing the bar 0 forward denomination 'tional selecting stop,

incline is divided off into a series of ste s or denominational stops b presenting s 0111- ders at graduated distances from an inner most position near the bar a to an outermost position, depending upon the number of steps in the series, seven being the number shown. Each of these stg-ps, in the direction of the feed of the carriage, is in length equal to one space on the scale, so that the seven steps shown will cover a space along the line of writing sufficient to Write any amount; less than ten million. By increasing the number of stepsor denominational stops in the series larger amounts may be written.

Underneath the machine and mounted in a suitable framework attached to the main frame is a series of horizontal push rods or selecting rods or devices e, each projecting through suitable hearings in the front part of the frame below the main keyboard, and carrying a button, key or .finger piece 6 against which the operator ma press his finger to force the rods inwar.. At their inner end portions the rods are provided with expansion springs c which return them to their normal or outer positions, each spring hearing at one endagainst the frame of the machine and at its opposite end against a collar secured to the associated push rod. Near their rear ends the rods pass through openings or notches fi in a bar. f which stands at right angles to the rods, and each rod carries a pin or projection f stsndin j in front of the bar and arranged from right to left at gradually increasing distances from the bar. The bar is carried by an upwardly extending lever g pivoted on the axis gin a portion of the frame, and engaging at its upper end with a plunger 2' arranged in a fore-and-aft position at the middle and back of the machine.

The plunger, which I shall hereinafter refor to as the detent, tabulating or-denominais mounted in a cylindricalbearing 11 strongly supported by a bracket 2' attached to the main frame. The hearing has an openingin which the end of the lever an opening in which the lever-fits in a manner permitting of the required movement;

The stop a is located in the'same horizontal I V t carriage ump at once to the proper position,

plane as the stop 6, and its forward end is provided with a flat working face or. surface 2", which in the operation of the device is struck by one of the shoulders on the stop 5.

The forward ends of the push rods 0 project respectively through openings or perforations j in a bar j arranged in front of the main frame. These openings are just l' 'ge enough to allow the buttons 6' to' pass into them. The buttons are somewhat smaller than the end of the fingerof the operator, so that when a push rod is forced inward, the finger of the operator finally 1 the machine Suppose it is desired to write 9 can vibrate, and the deten-thas znil ions (Whi the ar f, (and in fact it ma and soups part of the stroke the bar is thus made to accompany the button and the ,rod. To facilitate this movement of the bar in common vfor any'of the keys, it is provided at each end with guide rods j entering bearing apertures in the frame. It is also similarly guided by other rods 5} at each end which extend through the frame and to the rearof downwardly turned ends of a bai an axis h mounted in the frame. axis is fixed a bent; arm h reaching point immediately back of the release bar '0" on the carriage. It will be seen that by these connections parted to the key bar j will causethe arm h to strike the bar 0 and lift the feed rock out of engagement with the feed pinion 0 thus disengaging the carriage from 'its feed" ing devices. These connections are returned to their normal positions sfter the pressure of the finger is removed, b springs 1', each of which surrounds a rod 7' and hears at one end against a projection from the frame of the machine and at the other end against a collar on the associated rod 7' The operation can now be ex lained.

a bil statement or other docu out containing a column of figures.

or shoulder b will be opposits that point on the scale corres onding tothe point in t heline of Writing w ere the units ,column of figures is to occur in order to determine the columnar field; i. e., if the units column is to occur at letter space 55 of the line of writing, the stop will be adjusted so that the most rearward or outer step or shoulder will be opposite point 55 of the scale on the stop the innermost ste point 48 of the sea e because there are seven denominational stops on the stop member I). The seventh osition from the units is millions. once,- if the carriage is brought to a stop zit-48 on the scale, any amount in millions less than 10 can be printed at that point.

Let us now assume that, having written in shoe a. certain item, it is desired to have the outermost ste for writinc in the column the amount 7,564,326. Atfthe end of the written item the o orator will us-h the button e markedc h is the one on the extreme right, the'others being marked hun dred thousands, ten thousands, etcl, to units inward as far as it'will go. Since the in' f on this rod is the nearest one to be actually against the bar) the bar imme iately swings where they are hin ed to the,

it having To the to a an inward motion i1n-- One 0 the stops 6, is adjusted to the scale bar a in such a position that its- Bar a. This will bring or shoulder opposite-- accompanies the entire motion of the rod, theresult of which is that the detent 01' amount have been Written.

denominational selecting stop 27 is thrust forward as far as it can go, or to a position where its contact surface or point i will he in the path of movement of the innermost stepthe one located at ill on the scale of the stop rod---of the stop 5.

During the last part of the traverse of the button a. the finger of the operator engages with the common liey hair j and moves it im'urd. so that just as the detent reaches its intcnlled position the carriage is re- 1 E leased ctrom its feeding devices and the spring quickly moves the carriage to the left until it is detained at the letter space position 45 by the engagement of the inner step of the stop with the point of the detent. Upon r leasing the push rod (3, the detent returns to its normal retracted osition, the feed melt again engages the fH-t pinion and the" carriage is held until the operator strikes the T printing lrcy. whereupon the carriage feeds as usual to the next space (49) and the operator strikes the 5" key, and so on. until all of lhe figures in the Other Written matter may finish out the line, or. other amounts written in the same manner, by the aid of other stops I; placed at successive positions on the scale. It, in Writing the next. line of the docinneut. the amount to he Written in the first column is 903 the operator. when ready, will press the button c marked oundreds". whereupon. the detent will he thrust forward to a position Where its point will engage with the step opposite the 52% marl; on the scale and the carriage will he there arrested. The operator will then Write the amount 903 as before. Thus any amounts below 10 million can be readily Written in columns by a stop constructed as dcserihed. For larger amounts, the carriage can he set. hack one or more points after jumping to the million posi tion. or stops with more steps if can he used.

The modification illustrated in Fig. El is to adapt the devices ahove described to existing uuu-hincs of the same type, wherein the rear ends of the bank of key levers are covered by a frame plate A. This modification merely consists in pivoting the lever g. the bail IL and the feeding lever c in a.

single bracket A", and bending the lever 5 and bail to pass downward in front of the cover plate A.

In Figs. to 9. l have illuslirated my iuvention applied to what: is known as the hook typewriter or flat platen machine, in which the entire printing mechanism travels along the line of Writing While the paper or book remains stationary on a fixed platen. the carriage in this case carrying the printing instrumentalities. In these fig lures Ii indicates the frame of the carriage and K the stationary frame containing the platen. L indicates the character keys. The

Whenever they are struck.

atcd lengths, the shortest feed rack in this case is stationary and consists of a rod 1: having a rack on its upper surface which is engaged by a pinion k on a shaft la", the shaft carrying escape Wheel k and being mounted in a frame is pivoted at if to the carriage. The feed (logs are at the upper end of arm or dog rocker l1 pivoted to the carriage at Ir. and having a projection It? which is lifted by the character keys To disconnect the feeding devices from the rack. so as to permit the carriage to move freely under the pull of the spring drum Z, the frame A is tilted by means of the lever on. pivoted to the carriage at m and engaging with the frame It" by means of a pin and slot.

The regular scale bar of themaehinc is indicated at n; it is stationary and supported by brackets 11.. To this scale bar I iillilf'll the stop 0] stop members 0 similar in construction to the stop l) of the other nun chine, except that the steps or denomination stops :1". are in a vertical plane, the intention living; to set the lowest. step at the million position in the column and the highest step at the units position.

The dctcnt or denominatiimal selecting stop is in the form of :1 lug}; projecting: from a rectangular frame 72' mounted to slide ver tit-ally between guide wheels 11' on a. part p of the frame. A spring 9 holds the frame in its normal elevated position. Denominational tahnlator keys corresponding to keys 6 in the other machine are indicated by g each is provided with a button (1', upon which the words units, tens hundreds. etc.. will be marked. from right to left. These levers operate by depression and they all pass through an opening p in the frame 3), standing just above the lower member of said frame, and are attached respectively to pivotal shafts If mrmnted one behind the other in a. rearuard extension from the frame 72. Each of the sliai'ts is acted upon by a spring 9 which holds the lever in its elevated positiou. The buttons 1 are arranged in an oblique row so that they will stand above a certain portion of the frame, as shown in Fig. I

From the under side of each lever 1 there projects a lug q, said lugs being of grade: being at'the left, and immediately beneath these, is a lateral extension in of the release lever in.

The operation as far as it is necessary to describe is as follows: The keys (7 all have the same length of stroke, but their pivotal points being arranged at increasing distances beyond the frame p, said frame will be moved downward a different distance by each lever, so thati each lever is capable of setting the denominational selecting stop or detcnt y") opposite a difierent denominational stop of the stop member 0. Vi/hen an amount in the millions is to be written, the detent is moved to the lowest point by pressing on the key-to the right marked million. Near the end of the stroke of the key the lug g strikes and moves the release lever m and the carriage is ermitted 'to jump until it is stopped by t e detent coming into contact with the lowest step of of thekeys for setting the stopping mechanism is also capable of releasing the carriage.

When a separate key is used for the release it is evident that it may be manipulated by another finger of the o erator, if desired. This form can beapplie in Fig. 7 by dispensing with the extension at and simply pressing down on the lever m while still holding down one of the keys 9.

It is to be understood that the stops 6 or 0 with their steps or stops b and o'inay have their equivalents in various other specific forms; they mi ht, for instance, be in the form of pins ordugs projecting from a single block or stop member or they might be inserted in individual holes in the scale bar or otherwise attached thereto independently of each other, the generic idea being that the stop, as a whole, shall comprise a series of shoulders or abutments differently placed so that a single detent may be brought into line with any one of them to stop the carriage at a certain point on the line of writing and this is what is meant by the expression graduated stop in the claims which follow.

From the foregoing descriptiom it will be seen that the steps, shoulders or abutments of the so-called graduated stop constitute a series ofldenominational stops, whereas the single cotiperatin detent constitutes a tabulating stop and t e various keys for affording an arrest of the carria e at a predetermmed pointconstitute' ta ulating or denominational keys.
